sqlite does not treat # as the start of a to-end-of-line
comment. It cannot trivially be treated as such because at
startup sqlite parses statements containing the #-character.
Thus, only after sqlite has been initialized can it be treated
the same way as --.
Servers in MaxScale can encrypt the connections without client keys and
certificates. As keys and certificates are no longer required, the CA
certificate must always be initialized.
When a listener is created at runtime or SSL is being enabled for an
already created listener, the ssl_verify_peer_certificate parameter can
now be defined.
If a server responds when no response was expected, dump stored
statements. This should help deduce root causes of problems relating to
unexpected responses.
The tests can now wait for a number of monitor intervals. This removes the
need to have hard-coded sleeps in the code and makes monitor tests more
robust under heavier load.
Tracking how many times the monitor has performed its monitoring allows
the test framework to consistently wait for an event instead of waiting
for a hard-coded time period. The MaxCtrl `api get` command can be used to
easily extract the numeric value.
Increased the amount of time that the tests sleep while they wait for
states to change. This should make them more tolerant of server load by
allowing more time for things to settle down.
The code that selects the candidate backend always returned the root
master if the server bitmask contained the master bit. This should only be
done if the master bit is the only bit in the bitmask and when there are
other bits, the normal candidate selection code should be used.
Also added a query to the expanded test case to make sure the connection
actually works.
The test case now verifies that the servers are actually load balanced
correctly. This test reveals a problem in the readconnroute; the master is
always preferred over slaves if one is available with
router_options=master,slave.
The two operations return different types of results and need to be
treated differently in order for them to be handled correctly in 2.2.
This fixes the unexpected internal state errors that happened in all 2.2
versions due to a wrong assumption made by readwritesplit. This fix is not
necessary for newer versions as the LOAD DATA LOCAL INFILE processing is
done with a simpler, and more robust, method.
Commit 67386980e327ad063b24cb55971cf44f4930e241 caused the actual events
to be ignored. This meant that the larger event size was assumed for all
events. In most cases this works but it is not the correct way to do it.
It will not officially be released, but we must import the
documentation nonetheless as otherwise it's not possible to
refer to the 2.2.8 release notes and that's needed because the
bugs fixed in 2.2.8 are still fixed in 2.2.8 and not 2.2.9.
Up until 2.1.12, if it in the configuration file said
'router_options=slave', the master was used if there were no
slaves at session creation time.
That broke in 2.1.13 as a side-effect of MXS-1516 that checks
at routing time whether the server initially selected as master
still is the master.
Now the required server status is stored separately for each
session, so that if the master was chosen, even though we have
'router_options=slave', we can turn on the SERVER_MASTER bit.
That allows us to handle the case correctly in connection_is_valid().
Single spot where an existing hint ptr was overwritten. Removed gwbuf_add_hint()
because it was adding hints at the opposite end compared to functions in hint.h.
Added hint_splice() to replace.
Now, if a test is invoked with '-l', then MaxScale is assumed to
be running locally using a configuration file suitable for the
test that is invoked. Further, at the end of the test, the log
files of MaxScale are not downloaded (obviously).
As a side-effect, an environment variable no_maxscale_log_copy,
similar to the existing no_backend_log_copy, has been introduced
using which the downloading of maxscale log files unconditionally
can be prevented.
